Oh they track that, it's in their API as the "instrumentalness" score: https://developer.spotify.com/documentation/web-api/referenc...

The fact that they don't do anything with that information is unrelated.

Interesting, especially that it's a probability rather than a boolean! The line can be blurry sometimes (like in the example I mentioned), so it makes sense that it might not be possible to come up with a consistent way of classifying them that everyone would agree with.
